The bellows globe valve, also known as a bellows-sealed globe valve, creates a metal barrier between the fluid medium and the atmosphere through automatic roll welding, ensuring a design with zero leakage at the valve stem. The bellows globe valve features a bellows structure inside; the lower end of the stainless steel bellows is welded to the valve stem to prevent the process fluid from corroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. A dual-sealing design is employed; even if the bellows fail, the valve stem packing will prevent leakage. The bellows are welded to the valve stem to ensure stable operational performance and to avoid vibrations in the valve stem caused by vibrations of the valve plug. It is most suitable for pipelines carrying media such as steam, flammable and explosive substances, heat transfer oils, high-purity materials, and toxic substances.
